+	  an array for the first ten (dollar_vars) and a WORD_LIST * for the
+	  remaining (rest_of_args). Fixes performance issue with function calls
+	  and large numbers of positional parameters raised by
+	  Bize Ma <binaryzebra@gmail.com>
+	- {save,restore,free,free_saved}_dollar_vars: new functions to manage
+	  dollar_vars and dollar_arg_stack members. Need to keep these in sync
+	  with whatever remember_args does
+	- push_dollar_vars: use save_dollar_vars, which just copies pointers,
+	  and directly assign rest_of_args, without copying the words, to the
+	  dollar_arg_stack entry. Have to clear dollar_vars and rest_of_args
+	  with the assumption that callers will call remember_args(args, 1)
